I can't think of any breeds I am interested in that have something superficial that I don't like at the moment. Usually if I don't care for the look of the dog, it's also a breed I am uninterested in. With that said, part of the reason I didn't want an Aussie is because I prefer even just the look of tailed dogs. Or did, before I got one. Now I love the nub.

All of the breeds I do like, while I like them based on temperament, were also chosen with appearance in mind. That said, I don't want a really light eyed or blue eyed or bi-eyed dog. There is just something I don't care for. If someone offered me a puppy with light or blue eyes I would probably still take it and love it, but it's definitely not my preference and would take getting used to.

But yeah, those are more just general traits. I can't think of a breed example.

Super short coats. I'm actually really picky about
coat type overall. I like feathered coats, like on spaniels (and Brittanys.) I'm not sure I would want something super thick and long (Rough Collies), spitz fluffy/thick (Samoyeds, Keeshonds), wiry (terriers)... curly is ok, not as good as feathered but ok. Long haired retrievers are ok. Fluffy herders are ok (although some Aussies are too hairy for me.) Lab type is... meh. Ok but definitely not my preference. Super short I don't care for but I like a few breeds that have it.

Definitely. As a whole, I love Poodles personalities, but don't really like the looks of them, their hair, etc.

I typically am turned off by docked tails. It's a huge reason for not getting a Silky or Aussie from a reputable breeder for me. If I fell in love with a dog, I'm positive I could look pass the no-tail thing but in general, it's not something I would seek out.

Typically avoid brachycephalic breeds. I find a lot of them cute but I don't think I'd personally want a dog that looked like that, and I don't think I could deal with any issues that came with it.

Nothing TOO fluffy (full coated Pomeranians and a lot of Shelties are way too much floof for me) but I don't want close to naked/hairless either.

I also don't prefer the texture of some of the no-shedding curly hair where is it kinda dry and kinky curls. That being said my uncle has a black Standard Poodle with the most luxuriously soft coat. When freshly groomed it feels like crushed velvet. I could pet him all day long!

And though I would, and have, taken dogs with features on my 'not preferred' list the one major deal killer would be big slobbery jowls. The kind where you can see the pink of the inside of their mouth even when the jaw is totally closed. After working at a vets office and scraping cemented, dried drool off the ceiling and walls from a St. Bernard.... NOPE! Wouldn't have it in my house!

Gees... I sound picky... but aside from the slimy droolers, I'd take any dog that caught my heart

I don't really want a lab or golden because of how popular they are. It's stupid I know. I have other reasons for not liking labs now, goldens would still probably be a decent match, but the popularity thing (not just numbers but because people love them so much) is a turn off for me. It's like if he's super well behaved and nice people are going to assume it's because he's a golden not because I put a lot of work in. And that will bother me. It's a bad reason to avoid a breed, but I can't get over it.

This all the way. I don't like Labs or Goldens, and while some of it is superficial (because I'm not into solid colors, generally), a lot of it is a subtle resentment I'm kind of ashamed of... but can't get over. I so love pit bulls (especially flashy ones), but they're not even really my kind of dog. I'm not into happy, crazy, I-love-you-pet-me kinda dogs, really. If I was, I should go for Labs and Goldens, right? Because they're just that but (generally) without the cat and dog issues. But I'm so frustrated that everyone thinks retrievers are so naturally perfect, but I'm a groomer and see crazy, neurotic retrievers all the time, plenty of which have low bite inhibition. The pit bulls, well, they generally show amazing bite inhibition, but, you know... Oh well, getting off topic.
